net/mlx5: SF, Stop waiting for FW as teardown was called
[ Upstream commit 137cef6d55564fb687d12fbc5f85be43ff7b53a7 ]
When PF/VF teardown is called the driver sets the flag
MLX5_BREAK_FW_WAIT to stop waiting for FW loading and initializing. Same
should be applied to SF driver teardown to cut waiting time. On
mlx5_sf_dev_remove() set the flag before draining health WQ as recovery
flow may also wait for FW reloading while it is not relevant anymore.
